To compare the resolution I will never use full-image on screen, always use
100% or 200% pixel size. There is no scaling down which add blur. I may not
possible to compare screen with print but you can always compare screen to
screen (image to image). Ok, you may not be able to see the after print
result but should be good for image comparison.

Depends on the RIP engine, I don't see this a problem for Fuji Frontier,
when I specify direct-out there is no sharpen applied and no blur that I can
observe. Ok, I only made 8x10" output. Same for my Polaroid film recorder,
there should be no blur due to RIP since it output exact according to the
image original resolution, of course there is a little natural sharpness
reduction due to the imaging system loss (CRT, lens and film).

Yes, it may "look" good and I think it is not that important to your
customers as they do not see the original. For me I always want a more
faithful reproduction of the original.
